Siete Mares - Crewed Power Catamaran Charter

CAPTAIN November 2025 - January 2026
Bastian Tromp

Growing up in South Africa, Bastian was always surrounded by nature. He found creative ways to indulge in it: mountaineering, surfing, scuba diving, or free diving - anything that would bring him closer to the elements. His enduring love for the sea naturally led him to become a skipper.

Qualifying for his license on the challenging South African waters, Bastian´s training prepared him for whatever the ocean might bring. His first voyage was a daring Atlantic crossing, which paved the way for numerous other journeys. His skills and dedication quickly saw him advance to the position of Captain.

Bastian has completed two successful seasons in the Caribbean, offering luxury charter experiences that seamlessly blend his passions for sailing and connecting people with nature. Even on land, he is often sought to lead explorations and camping trips, making chartering a natural extension of his abilities.

Bastian is truly passionate about the sea, nature, and our connection to it. An avid free diver, he loves the tranquility that comes with being underwater, appreciating the physical and mental challenges the sport demands while exploring a whole other world beneath the surface. He has an uncanny knack for finding the perfect equation for a divine sunset. For him, providing an unforgettable experience on the sea is a true joy, blending adventure and relaxation in perfect harmony.

CAPTAIN February 2026-
Tiago Farto Silva
Tiago was born in Lisbon and grew up in Peniche, a surf town on Portugal’s west coast. From a young age he was drawn to the water - sailing optimists and 420s, surfing, and swimming whenever he could. In his twenties, he worked as a surf instructor at Baleal Surfcamp, teaching both kids and adults from all over Europe how to catch their first wave.

He later studied at the Nautical University in Lisbon, earning a degree in Nautical Sciences before joining the Norwegian merchant navy as a deck officer. His career took him across the North Sea, Gulf of Mexico, and South Atlantic aboard chemical tankers, seismic vessels, and ROV ships. In 2019, Tiago returned to Europe and began working charters in Greece and Croatia, and it also brought him to Tahiti and the Caribbean.
He loves that chartering allowed him to bring together many of his passions - instructing, navigating, exploring, and life on the water - and he’s been doing it ever since.

Having spent most of his life at sea, Tiago is a confident and experienced captain who enjoys sharing his knowledge and showing others the beauty of life on the ocean.
Calm, capable, and deeply experienced, Tiago makes every guest feel safe, relaxed, and well taken care of.

CHEF
Kiki Bouman
Kiki is a chef from the Netherlands who started her career in restaurant kitchens, working her way up from line cook to sous chef. After eight years in the fast-paced world of fine dining, she decided it was time for a new adventure. In 2020 she swapped land-based kitchens for ocean-view galleys - and hasn’t looked back since.

Food and cooking are at the heart of everything Kiki does. She thrives on challenges and embraces the belief that there is always more to learn in the kitchen. Her style is bold, vibrant, flavor-driven and she loves to experiment with unique ingredients.
For Kiki, the dinner table is where the best memories are made, and her mission is to create incredible dining experiences for every guest.

When she isn’t in the galley, Kiki loves exploring new cities and immersing herself in all things culinary - whether it’s wine tastings, dining at Michelin-starred restaurants or enjoying local food culture. She also dreams of opening her own place one day.
